Title: Process for controlling calcium sulphate scale deposition in sea water heating
IPC: C02F5/08
Filed: 1958-09-18
Abstract: A process for preventing the formation of hard calcium sulphate scale on equipment for heating sea water expecially for use in the Frasch sulphur mining process in which water at 315 DEG F. is pumped into the mine, comprises supersaturating the sea water with respect to calcium carbonate and/or magnesium hydroxide by addition of sodium carbonate and/or sodium hydroxide at a temperature below the saturation temperature with respect to calcium sulphate to precipitate the salts in the form of nuclei, keeping the nuclei in suspension to serve as nucleation points for calcium sulphate and then heating the sea water to a temperature at which the calcium sulphate precipitates.  As the water reaches the said temperature the calcium sulphate deposits on the precipitated calcium carbonate or magnesium hydroxide crystals rather than as a scale on the surfaces of the heating equipment. In the sulphur mining process referred to above the heated water in which the scale forming salts are suspended is then pumped into the mine avoiding the frequent shutdowns previously necessary for removing scale from the heating plant.

Title: Manufacture of amines
Filed: 1955-10-20
Abstract: Primary C1-C8 amines are prepared by reacting the corresponding alcohols (primary or secondary) with ammonia in the presence of a hydrogen-transfer catalyst and a hydrogen-accepting substance.  The latter is preferably the aldehyde or ketone corresponding to the alcohol used and may be added at the beginning or formed in situ by oxidation of the alcohol; it may be present to the extent of 5-30 per cent of the weight of the alcohol.  The operating temperature may be 60-180 DEG  C.  Suitable catalysts are nickel, cobalt, reduced copper or a noble metal such as platinum or palladium, if desired on a support.  Examples show the production of isopropylamine and butylamine from isopropanol and butyraldehyde respectively, in one case with a little di-isopropylamine as by-product.

Abstract: 176,047. Graf, F., and Svensson, J. W. Oct. 25, 1920. Clutches, friction.-In expanding-band friction clutches, one end of the band is rigidly correlated with the driving-shaft, and the two ends are separated for engagement by a cam which is turned by an inertial weight during acceleration of the driving-shaft. A member 3, keyed to the driving-shaft 1, is integral with the clutch-band 9, which runs with small clearance in a driven casing 5 loosely mounted on a boss 4 of the part 3, and may carry a gear-wheel 7. As shown in Fig. 3, the band is divided by a cut 10, in which is formed an oval enlargement 11 to receive a cam 12, Fig. 1. The direction of the slot 10 is appropriate for clockwise rotation of the clutch. The pivot 13 of the cam is journaled in a casing 14 secured to the member 3 and has clamped to it, by a bolt 17, a weight 16, which is slotted, as shown at 18, to clear the shaft 1, so that it may swing to engage and disengage the clutch with changes of speed of the driving-shaft.

Title: Improvements in yarn trapping and severing devices for circular knitting machines

IPC: D04B35/00
Filed: 1952-12-01
Abstract: 742,536. Knitting-machines. STIBBE & CO., Ltd., G. Dec. 1, 1953 [Dec. 1, 1952; March 13, 1953], Nos. 30376/52 and 6991/53. Class 74 (2). A trapping and severing device for use in splicing on selected needles, comprises blades 6, 7, 8 contained in a groove 2, ending in a slot 3, in a, relatively slender holder 1, there being provision for relative movement between the holder 1 with the blades 6 and 7 on the one hand and the blade 8 on the other. When the blade 8 is the fixed member, the yarn is cut consistently close to the needles. As here shown, it is the blade 8 which is movable. The blades 6, 7 are located by lugs 9 in a slot 5 in the holder and at transverse cutting and trapping edges on their lower ends 6c, 7b coact with the sharpened top edge of a lateral extension 8b on the blade 8. By means of an eye 8e, the blade 8 can be raised or lowered, to sever and trap or to release the thread, within limits determined by shoulders 8c, 8f. The holder 1 is contained in a blade retaining housing 11, itself contained in the bossed end of a lever 12 pivoted on the latch ring post 8 rocked by the main control unit, through link 21, to raise and lower the trapping and severing unit to inoperative and operative positions. The butts. of jacks 16 associated with needles which are to take a splicing thread, pass down a cam 26 on to a levelling cam 27 and, when the trapping and severing unit is operative, pass under a cam 28 which, by reason of a part 28a thereon, is raised by the leading butt and so, through a lever 29, Bowden cable 30 and a bell-crank lever 10, depresses the blade 8, to release the previously trapped thread. The cam 28 is held lifted whilst the succeeding butts of the group pass and then falls, allowing a spring 15 to lift the blade 8 and so trap and sever the thread. As the unit is raised to inoperative position, before knitting a heel or toe, an arm 31 on the link 21 rocks the lever 29, to raise the cam 28 so that it cannot be subject to the action of jack butts : the splicing thread may then be taken into a main trapper provided on the dial cap of the welt mechanism.

Paper pulp supplied from a flow-box 15 to the wire-cloth 10 above an open breast roll 11 of a Fourdrinier paper-making machine is subjected to suction through the roll 11 and wire 10, the roll 11 being partly surrounded by a suction save-all enclosure 18; the wire 10, at its entry into the enclosure passing through an adjustable gap G which acts as a partial vacuum seal. The wire 10 leaving the roll 11 passes between side seals 23 and above an adjustable deflector 21 for removing water from beneath the wire-cloth, a further deflector 27 being provided adjacent a table roll 12. In modifications, the gap G may have corrugated surfaces on each side; or the gap may be on one side of a wire-guide roll adjoining which is a doctor with a sealing tube; or the gap G may be formed as a water seal. In other modifications, there is a succession of suction zones with table rolls 12 and deflectors 27 extending along the underside of the wirecloth. The table roll 12 may be solid, dandy type, or grooved. Specification 871,247 is referred to.

Inking means for printing presses comprises a pair of parallel contra-rotatable horizontallydisposed rollers disposed in rolling contact with each other and forming a nip and a channel at said nip into which ink is introduced to build up in said channel, the ends of the channel being unobstructed to allow surplus ink to flow freely out of the channel ends, means for leading surplus ink away from the ends of the channels, and one or more filters at one or more positions in ink-circulating means between the means for leading away surplus ink and the means for introducing ink into the channel. Ink from a fountain 14, Fig. 1, having a waterjacket 24 is forced by a pump 17 into a pipe 15 leading to a pipe 16, Figs. 1 and 2, having orifices therein through which the ink is forced into the nip 13 between the rollers 11, 12, one of which is in contact with the printing roller. Surplus ink removed from the ends of the channel by scrapers 21 passes by means of inlet shoots 20 into a duct 19 whence it is returned by a pipe 23 to the fountain. Surplus ink passing through the nip also passes to the duct. Ink passing through the pipe 16 and not issuing through the orifices passes to the duct through a cook 22, which adjusts the supply to the nip. The pipe 15 contains a duplex filter 25 having two filter elements, one of which can be removed for cleaning, while the other is in use. Alternatively, the filter may be in the shoots 19 or the return pipe.
